Class abdialog.Dialog

A modal dialog. A modal dialog by default always has a Dialog.okButton and a Dialog.cancelButton at its bottom, and a container Dialog.box where the actual dialog widgets should be added to. On S60 devices, ok and cancel are also invoked by the two option keys.

The following properties are taken from abguibase.theme:

Key	Meaning
`dialogbg`	abguibase.Background for dialogs
`dialoginset`	inset of dialog box

Once the dialog has been set up, Dialog.run() shows it to the user and waits for ok or cancel to be pressed before returning to the previous view.

Here is a complete example:

query:abdialog.Dialog=abdialog.Dialog(2);
query.box.add(gui.Label("Name:", gui.RIGHT|gui.VCENTER));
name:gui.TextField=gui.TextField()
query.box.add(name);
query.setCentered(); // optional
if query.run() then
  print name.text+" was entered"
end
